Halloween may have already come and gone, but that didn’t stop Kelly Osbourne from throwing her son Sidney a spook-tacular celebration for his first birthday on Sunday.
Osbourne, 39, was spotted arriving to the lavish celebrations in a black dress with lace detailing and the birthday boy in her arms.
Her lilac hued locks were slicked up into a neat little bun and her complexion radiated with a dramatic swipe of eye makeup and rosy blush.
Sidney was looking cute in a smart black-and-white outfit with a pacifier in his mouth.
Osbourne, whose father is rock royalty Ozzy Osbourne, was trailed by a camera crew who were capturing the special day.

Her brother, Jack Osbourne, was also seen arriving to the festivities. He donned a plaid button down, off-white trousers, and had his hair slicked back.
On Instagram, Kelly showed off the spooky celebrations – complete with smoky cauldrons, skulls, and plenty of ghosts.
Set to the track Monster Mash, Kelly captioned the video: ‘Thank you @littlespoon for making Sidney’s birthday so special! His favorite go to healthy snacks were a hit for him, his friends, and even the adults.’
She also shared a precious photo of him beaming with happiness in the bath as she gushed about her baby boy.
‘This past year has been the most magical year of my life for one reason. That reason is you baby Sidney. To watch you grow, learn and become a little man is the greatest joy I have ever felt,’ she wrote.
‘The most magical bond I have ever experienced is the bond I feel with you. Before you love was just a word that I thought I understood.
‘NOW I truly understand what love is. I am forever indebted to you for teaching me the beauty meaning and truth of love. What more can I say other than I love you. Happy birthday sweet price. We made it on our first trip around the sun together.’
Kelly’s svelte frame was achieved less than a year after giving birth to her son Sidney.

Speaking to Vanderpump Rules star Scheana Shay on her podcast last month, Kelly admitted that she ‘went a little too far’ losing her baby weight.
She told Shay — who is also a mother-of-one — that she went ‘on a mission’ to shed the pregnancy pounds but lost more than she’d needed to.
‘[I was] on a mission after having the baby to lose all [my] baby weight,’ she said.
‘Then I was like, “Well, I lost all the baby weight. Let’s see how far I can go with it.” And then went a little too far.’

Kelly has had lifelong battle with weight which previously drove her to seek surgical intervention.
In 2020, the television personality revealed that she had quietly undergone gastric sleeve surgery two years before, leading to a jaw-dropping 85lb weight loss.
‘I had surgery,’ Kelly stated in an interview. ‘I don’t give a f*** what anyone has to say. I did it, I’m proud of it, they can suck s****. I did the gastric sleeve.’

Kelly first announced that she was expecting in May 2022 in an Instagram post.
‘I know that I have been very quiet these past few months so I thought I would share with you all as to why,’ she wrote. ‘I am over the moon to announce that I am going to be a Mumma. To say that I am happy does not quite cut it. I am ecstatic!’
While she has yet confirmed the exact date of Sidney’s birth, Kelly did tease on Instagram in November that she was about to go into labor.
‘Ok,’ she wrote in white against a simple black background. ‘Here we go.’
